  1. I recently had my 2004 CTT in the dealer to track down an oil leak from the front left corner of the cayenne, the dealer indicated the oil leak conditions could stemmed from either the left turbo or a faulty oil seperator (located in the valve cover). I've already replace my oil seperator 2 1/2 years ago and no smoke has been observed when the turbo's kick in. Therefore, it looks like my left turbo is leaking and needs to be replaced. My plan is to remove the left turbo and have it rebuild for under $500 vs. a new OEM turbo for $1900. My question to forum is, can the turbocharger be replace wi
  2. Hello everyone, Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.
  3. Just wanted to say thanks to the community helped answer some questions about the scoring on my 2008 CTT 957. My next question is, does anyone know where I may purchase a complete engine seals and gasket kit for a 2008 Cayenne Turbo? Or if these are unavailable as a whole unit, had anyone rebuilt their engine from the cylinder scoring or something similar and have a parts list of required seals and gaskets which need changed? Additionally, are there any other suggestions on parts that I should change some I'll have the motor apart? Anything would help at this point. Thanks
  4. Hi - on my 06 CTTS, over the last few months I noticed occasionally awful smell inside the cabin while driving. My research so far indicates that it is emitted from vents when AC system is on. Believe it smells like sth. burned, and is not present when I switch AC system completely off. Did anybody experience this before on a 955 Cayenne, Turbo or Turbo S ? Thanks in advance. PS.: side note. It may be coincidence or completely unrelated, but as far as electrical problems I am noticing for about comparable amount of time that the horn is dead (silence when pressing the steering wheel ce
  5. Hi mates, I purchased last week a 996 Turbo (2002). Unfortunetly there was neither an operation manual of the car nor of the PCM System. Is there a chance to get one (as orig. book or PDF file) in english or german?
  6. Hi everyone. We have a 1982 Kremer built 930 that we have absolutely no documentation about. Does anyone out there know what differentiates a Kremer 930 from a regular 930? The engine is about to be rebuilt (broken rocker, detonation evidence on all pistons, broken piston rings, crack in head around valve guide and a big end that wasn't going to last much longer) and I'm wondering if anyone can point me in the right direction for sourcing parts and information. Someone has done work on the engne at some stage and removed the turbo oil scavenge pump and fittings so we're looking for that sy
  7. Hello, I recently bought a Cayenne S 4.8 from 2008. After a month the HPFP went down so I repaired that (900 euro), no problem if it is just a standalone incident but it seems to be very common for the 4.8 engines. Mine was already replaced with the former owner in 2010 and 2011. My engine was replaced in 2010 by Porsche and now this engine has around 100k kms (so the second HPFP failed just after a couple of thousand miles). This made me thinking about the build quality of the Porsche engines. The HPFP is not Porsche made I guess (Continental is written on it) but if "I would be" Porsche
  8. Hi, I'd like to ask a question that has been asked, discussed, youtube videoed etc... My apologies, but I've read most of them and haven't found anything similar. I'm looking at a 2004-2006 Cayenne Turbo that I don't want to turn into an engine money pit. I've listened to 8, all cold and most have a very slight knock on the drivers side of the engine. I'm wondering if this is the beginning to the end or some explainable sound. You can only hear it once it drops to a low idle. I went to my local dealer in Denver and they stated they have no way to diagnose, would not perform a new car ins
  9. Hello Members, Just found some instructions for changing spark plugs without having to remove the rear bumper/license plate light, and intercoolers. The process is more or less - remove rear wheels, and then remove various heat shields - does this seem viable? Here is the link I found: http://bd8ba3c866c8cbc330ab-7b26c6f3e01bf511d4da3315c66902d6.r6.cf1.rackcdn.com/Porsche996TMajorMaintenanceupdate.pdf Using this method will save a bunch of time let me know, ewholz
  10. I am bit confused because 2 different Porsche Indys had different suggestions to the problem. My car, when cold after sitting 5-6 days when I get in and start it, it starts flawlessly. After driving for about 5-10 minutes to get to the grocery or gas station the car needs 2-3 turns of the key to start. Sometimes it starts with 1st turn (very rare when hot). Battery 6 months old, although it doesn't seem as a power problem. When the car was in for a PDCC line leak, I mentioned the problem to the mechanic who noticed it and told me next time we should clean the starter (don't know what that me
  11. Just purchased a 2008 CTTS and the previous owner is running a staggered set up Front:275/40/20 Rear:315/35/20. The current tyres Goodyear Wrangler F1 need replacement and I would appreciate some suggestions from the members here. -The 1st and expensive choice: P-Zeros at 1250 Euros -Continental Contisport SUV: at around the same price -And a guy at a local store suggested Atturos AZ850 which are at around 630 Euros. What do you guys think? Any other suggestions?? Thanks in advance
  12. Hi to all in the forum, I am Chris from Greece and I am looking for a piece of advice. I have found a CTT 2005 with 35000 miles that a bank sells after being abandoned for 2+ years and not in garage. As the price is tempting and I am looking forward to spend some cash to bring back to the road. What do you thing I must expect in terms of Service, taking for granted that all liquids in engine and trans are going to be replaced, new tyres etc. P.S. probably a conversion to 2007 F/L look is a thought. http://www.renntech.org/forums/uploads/downloadedimages/edit.gif' title="Edit/Delete Messag
  13. Hi, I'm new to this website and new to Porsche ownership and was hoping that I could get some help with an issue that's just occurred with the coolant expansion tank of my 04 Cayenne Turbo. I recently purchased this vehicle back in June after selling my range rover. At the time I did quite a bit of research and discovered the issues with the coolant pipes, carden shaft bush, ignition coils etc that were prevalent with the early Cayenne models. After viewing a few vehicles that were less than desirable I eventually found a Cayenne in pristine condition, and more importantly with all the a
  14. Hi, I need winter tires on my 1999 Porsche 996 Carrera. I found some used 19" (99736215602) ET57 8x19 front with 225/40r19 and (99736216202) ET51 11x19 rear with 255/35r19. My question is, will these fit my carrera? The owner have had it on a 996 Turbo (not 997 Turbo). Thanks :notworthy:
  15. Hi everyone, Recently been dealing with a 996 TT with excessive smoke... After some turbo rebuilding the smoke from the tailpipe stopped but they started leaking externally. After some research turbos are not necessarily oil tight..meaning that the oil is not getting evacuated from the turbo reservoirs. More time and research led me to checking the turbo scavenge pump (yes they have 3, 1 on each head and one in the center for the turbos) Attached are the photos of some carnage, basically the drive off the intermediate shaft is stripped. I'm hoping one of the gurus will chime in on the ex
  16. Spent the afternoon under the front N/S corner of the 04 Cayenne Turbo, looking to replace the seals on the boost hoses and dump valve. When unclipping the bottom turbo hose from the intercooler, I was stunned to find at least 1/4 litre of oil pour out of the hose onto the floor. In all my years, I've never taken a hose off a turbo and seen that much oil. Has anyone else on here taken the hose off the bottom of the intercooler on the N/S (Drivers side US & Europe, Passenger side UK) and experenced it full of oil? I'm worried about the state of the oil seals on the N/S turbo.
  17. Hi Everyone, I have been lurking in the forum for a while and soaking up all I can gather about the Cayenne. Thanks for making this forum an amazing repository for all things Porsche. I have been in the market for a truck for sometime now. My truck of choice was the full sized Range Rover Supercharged..however, I took my wife for a test drive of the Cayenne and she was completely blown away. I was sold as well on the on road behavior. Things that are important to me 1. Character and Driveability 2. Reliability 3. Gas mileage to some extent (dont want a 11mpg truck but 16 - 20 ish is
  18. I have a 2005 cayenne turbo. When I accelorate it seems as if the car builds itself up then takes off, but when the RPM passes 6 and enters into the red, the truck seems to jump or hesitate, almost like I'm slamming on the brakes then it takes off again. The engine light comes and goes and every time it throws p0016 which is camshaft and crankshaft position sensors. I had it checked out and was told there is no way to diagnose it as the timing belt without taking out the turbos out and blah blah blah. So, I am left to replace both sensors and go from there. What does this sound like? Help plea
  19. I see a lot of bearings for sale on eBay for $71-90 but I regret I can find no actual procedure on the forum for hoe to actually replace the bearing. I see how to remove the shaft which is simple... Just need to know how to separate the shaft at the pivot point... Thanks!
  20. Didn't find any TT or awd specific posts regarding this, so I was hoping I could get a quick walk through of the front control arm replacement procedure. My car is an '01 996TT. I found this, and the control arm and track arm look very similar in the picture so I am guessing it is closely resembling ours? ( http://kevingosselin.blogspot.com/2009/08/boxster-control-arm-replacment-in-total.html ) But that link doesn't deal with any front half shafts. Do I need to remove the hub assembly to do my front control arms? Should I have new CV boots/clamps standing by? Thanks for any pointers! -Conn

I just ordered the parts today so it might be self explanatory but I didn't see where the spring would go for example. Any digrams or pictures would be greatly apprecaited. Thanks in advance.
  23. hi! Does anyone have a wiring diagram for 996 turbo 2001 they are willing to share with me? My right rear foglight dosen't work, I have measured and there is no 12V, I have ground on the brown cable, but no power on the gray cable.. so I want to find the other connection points to figure out why I don't have 12V on the gray cable.. and yes the fuse is ok :) hope someone can help!

  24. Need your guys help & expertise please I've been trying to find the cause of the P0299 underboost code for a while now and after randomly stabbing in the dark by changing intercooler, Y-piece, hoses, N75 valve, I read a really good post on here (in the 996 section) about pressure testing. I've spent the last few weeks, getting a gauge, schrader valve, fittings, and various sizes of hose so I can T into the lines of the turbo system (it was the offside turbo to bottom of the N75 I actually Tee'd into) and yesterday, tried to test the system using my compressor.

  25. Hi I have a question please I wonder if someone can answer? I have a 2004/05 4.5V8 Twin Turbo, Tiptronic. When driving normally, leaving the car in normal D (Drive) the car is quick to shift gears between 2000 and 3000rpm, going up the gears as quickly as it can, often leaving me in too high a gear and being very sluggish. I've recently noticed, if I turn off the PSM button, the car shifts alot later in the revs, between 3500 and 4500 and in doing so, always sits just on the turbo and feels so much more responsive. flick the PSM back on, and the car returns back to its sluggish ways
